Beer Gravity Calculator

The grains, extracts and fermentable sugars you use contribute sugars to the wort. These
sugars are converted to alcohol by the yeast during fermentation. You can use
this calculator to estimate the intial gravity, final gravity and the alcohol by volume
of your beer.

Mash effeciency

How does this work?

Each grain, extract or sugar has a certain amount of potential sugar which can
be extracted through the mashing process. You can see this amount in the
grains/sugars listing under max PPG (points per gallon).
This calculation sums the possible sugars which could be extracted and based on
the size of the batch it estimates the original gravity.
